| deep white layer of superior colliculus | See: gray layer of superior colliculus. (05 Mar 2000) |
| differential white blood count | An estimate of the percentage of white blood cell types which make up the total white blood cell count. (05 Mar 2000) |
| egg white | The white of an egg, especially a chicken's egg, used in cooking. It contains albumin. (12 Dec 1998) |
| egg-white injury | <syndrome> Dermatitis, loss of hair, and loss of muscle coordination, produced in rats by diets containing large amounts of raw egg white, the avidin of which combines with biotin producing a deficiency of the latter. Synonym: egg-white injury. (05 Mar 2000) |
| egg-white syndrome | <syndrome> Dermatitis, loss of hair, and loss of muscle coordination, produced in rats by diets containing large amounts of raw egg white, the avidin of which combines with biotin producing a deficiency of the latter. Synonym: egg-white injury. (05 Mar 2000) |
| familial white folded dysplasia | An autosomal dominant condition of the oral cavity characterised by soft, white or opalescent, thickened and corrugated folds of mucous membrane; other mucosal sites are occasionally involved simultaneously. Synonym: familial white folded dysplasia, oral epithelial nevus. (05 Mar 2000) |
| zinc white | <chemical> A mild astringent and topical protectant with some antiseptic action. It is also used in bandages, pastes, ointments, dental cements, and as a sunblock. Pharmacological action: dermatologic agents, sunscreening agents. Chemical name: Zinc oxide (ZnO) (12 Dec 1998) |
| Lee-White method | A method for determining coagulation time of venous blood in tubes of standard bore at body temperature. (05 Mar 2000) |
| accelerated reaction | A response occurring in a shorter time than expected; the cutaneous manifestations occurring during the period between the second and tenth day following smallpox vaccination; because it is intermediate between a primary reaction and an immediate reaction, it is regarded as evidence of some degree of resistance. Synonym: vaccinoid reaction. (05 Mar 2000) |
| acid reaction | Any test by which an acid reaction is recognised such as the change of blue litmus paper to red, an excess of hydrogen ions over hydroxide ions in aqueous solution indicated by a pH value less than 7 (at 22캜). Compare: dissociation constant of water. (05 Mar 2000) |
| acute-phase reaction | <immunology, rheumatology> Refers to the changes in synthesis of certain proteins within the serum during an inflammatory response, which provides rapid protection for the host against microorganisms via non-specific defense mechanisms. It consists of fever, an increase in inflammatory humoral factors, and an increased synthesis by hepatocytes of a number of proteins or glycoproteins usually found in the plasma; the reaction is mediated by endogenous pyrogens, the hypothalamus, adrenal hormones, and other factors. (12 Jul 2000) |
| acute situational reaction | An acute emotional reaction related to extreme environmental stress. Synonym: acute situational reaction. (05 Mar 2000) |
| acute stress reaction | A sudden bout of anxiety that is often accompanied by the features of hyperventilation (tingling around mouth and in fingertips, rapid breathing, faintness or fainting). (27 Sep 1997) |
| addition reaction | <chemistry> Any reaction in which two chemicals combine to form a single chemical. (15 Jan 1998) |
